OBJECTIVE
To compare the accuracy of 3 computer-aided surgery systems for maxillofacial reconstruction.
DESIGN
Evaluation of 3 computer-aided surgery systems: StealthStation, VectorVision, and Voxim.
SETTING
The University of California, Davis, Department of Otolaryngology computer-aided surgery laboratory.
PARTICIPANTS
Four fresh cadaveric heads.
MAIN OUTCOME MEASURE
Mean target registration error.
RESULTS
The StealthStation was the most accurate (mean [SD] target registration error, 1.00 [0.04] mm), followed by VectorVision (1.13 [0.05] mm) and then Voxim (1.34 [0.04] mm). All values met statistical significance (P < .05).
CONCLUSIONS
Measurable accuracy differences were found among the navigation systems evaluated. The StealthStation was the most accurate. However, the differences are small, and the clinical significance for maxillofacial reconstruction is negligible.
目的
比较3种计算机辅助手术系统用于颌面重建的准确性。
设计
对3种计算机辅助手术系统进行评估：StealthStation、VectorVision和Voxim。
地点
加利福尼亚大学戴维斯分校耳鼻喉科计算机辅助手术实验室。
参与者
4个新鲜尸体头部。
主要观察指标
平均目标配准误差。
结果
StealthStation最准确（平均[标准差]目标配准误差为1.00[0.04]mm），其次是VectorVision（1.13[0.05]mm），然后是Voxim（1.34[0.04]mm）。所有数值均具有统计学意义（P<0.05）。
结论
在所评估的导航系统之间发现了可测量的准确性差异。StealthStation最准确。然而，差异很小，对颌面重建的临床意义可忽略不计。
